In one of the various embodiments of the present disclosure, currently connected electronic devices are classified based on flowcharts illustrated in FIGS. 3A, 3B, and 3C.

Referring to FIG. 3A, the AP 210 of the first electronic device 101 may search for second electronic devices having one or more connection logs through the BT module 225 in operation 301. The first electronic device 101 may identify a BT communication log list to search for the second electronic devices having the connection log.

The AP 210 of the first electronic device 101 may classify, as group B, the remaining electronic devices except for the non-connected second electronic device 104 among the second electronic devices classified as group A in operation 305. Whether the second electronic devices are in a non-connected state may be determined through sensing by sensors of the sensor modules of the second electronic devices. Among the sensors of the sensor module, particularly, a proximity sensor may determine whether the second electronic device is in a connected state. In operation 307, the AP 210 of the first electronic device 101 may communicate with the second electronic devices of group B through BT communication.

Referring to FIG. 3B, the AP 210 of the first electronic device 101 may search for second electronic devices having one or more connection logs through the BT module 225 in operation 311. The AP 210 of the first electronic device 101 may identify a BT communication log list to search for the second electronic devices having the connection log. The AP 210 of the first electronic device 101 may classify, as group A, the remaining electronic devices except for the non-connected second electronic device 104 among the found second electronic devices in operation 313. Whether the second electronic devices are connected or not may be determined through sensing by sensors of the sensor modules of the second electronic devices. Among the sensors of the sensor module, particularly, a proximity sensor may determine whether the second electronic device is in a connected state. In operation 315, the AP 210 of the first electronic device 101 may classify second electronic devices, which can receive a data output command signal and output the data, among the second electronic device of group A, and may designate the classified second electronic devices as group B. In operation 317, the AP 210 of the first electronic device 101 may communicate with the second electronic devices of group B.

Referring to FIG. 3C, the AP 210 of the first electronic device 101 may search for devices using the same account among the second electronic devices in operation 321. The AP 210 of the first electronic device 101 may classify, as group A, the remaining electronic devices except for the second electronic device 104, which is not connected to the first electronic device 101, among the second electronic devices using the same account in operation 323. Whether the second electronic devices are in a non-connected state may be determined through sensing by sensors of the sensor modules of the second electronic devices. Among the sensors of the sensor module, particularly, a proximity sensor may determine whether the second electronic device is a connected state. In operation 325, the AP 210 of the first electronic device 101 may classify second electronic devices, which can receive a data output command signal and output the data, among the second electronic device of group A, and may designate the classified second electronic devices as group B. In operation 327, the AP 210 of the first electronic device 101 may communicate with the second electronic devices of group B by controlling the BT module 225.

In one of the various embodiments of the present disclosure, the optimal second electronic device 104 may be determined by identifying types of data to be output and states of the second electronic devices to output the data.

For example, when the AP 210 of the first electronic device 101 is to output vibrations, the AP 210 may receive corresponding sensor values from sensor modules of the second electronic devices, particularly, a gyro sensor or an acceleration sensor to detect motions of the second electronic devices. The AP 210 of the first electronic device 101 may determine through the sensor values whether the second electronic devices are currently moving or not. Since the AP 210 of the first electronic device 101 desires to output the vibrations, the AP 210 may select the second electronic device 104 having the smallest motion, that is, the smallest sensor value received from the sensor module. The AP 210 of the first electronic device 101 may control the BT module 225 to transmit a vibration output command signal to the selected second electronic device 104. For example, when the user is walking, the AP 210 of the first electronic device 101 may transmit a signal for outputting data to a wristband which moves relatively less than a shoe rather than outputting data through the shoe.

For example, when the AP 210 of the first electronic device 101 desires to output a voice, the AP 210 may select a device having the smallest ambient noise based on input values of microphones of the second electronic devices having the microphones. Further, the AP 210 may select the second electronic device 104 that can output a volume level of the voice to be output from the first electronic device 101.

For example, when the AP 210 of the first electronic device 101 desires to output visual information such as a color, the AP 210 may recognize a state of the second electronic device 104 through the sensor modules of the second electronic devices, particularly, an IR sensor or an illumination sensor. Alternatively, the recognition is made through a combination of the IR sensor and the illumination sensor. Further, when the second electronic device 104 includes a camera, the AP 210 of the first electronic device 101 may recognize whether the user looks at the second electronic device 104. The AP 210 of the first electronic device 101 may select the second electronic device 104 at which the user looks or the second electronic device 104 having small obstructions from data of the sensors. When the user currently puts their hands into their pockets, the AP 210 of the first electronic device 101 may select a shoe or a necklace which is relatively less obstructed without displaying visual information through a ring. The shoe or necklace which is the selected second electronic device 104 may display the visual information received from the second electronic device 104 by controlling an LED.

One of the various embodiments of the present disclosure may correspond to all embodiments in common.

The AP 210 of the first electronic device 101 may select the second electronic device 104 to output data. Alternatively, the AP 210 of the first electronic device 101 may select the second electronic device 104 to output data by comparing pieces of data between the second electronic devices. When selecting the second electronic device 104, the AP 210 of the first electronic device 101 may identify a battery state. The second electronic device 104 may require a significant amount of power consumption to display data or perform an operation according to the data. Accordingly, in selecting the second electronic device 104, identifying whether the battery state is higher than or equal to a predetermined level is a top priority.

One of the various embodiments of the present disclosure may be described through Table 1. Table 1 shows optimal output data of second electronic devices according to an embodiment of the present disclosure.

TABLE 1 Second electronic device Output data Shoe Number of steps Headband Bone conduction/Volume Wristband Pulse/Heartbeat Ring Pulse/Heartbeat

Referring to Table 1, the type of optimal data according to the second electronic device 104 may be pre-defined in various embodiments of the present disclosure. For example, the AP 210 of the first electronic device 101 may instruct the second electronic devices to transmit data related to the user's pulse. The second electronic devices, for example, the shoe and the wristband in Table 1 may attempt to transmit the data related to the signal received from the first electronic device 101. The second electronic devices may transmit the data related to the signal received from the first electronic device 101 to the first electronic device 101. The AP 210 of the first electronic device 101 may determine data which is most suitable for the user's pulse among the received data. Since the wristband is a device suitable for outputting the user's pulse between the shoe and the wristband, the AP 210 of the first electronic device 101 may select the wristband and control the display unit to output data received from the wristband for the user or perform an operation for displaying the data.

Further, the second electronic devices having received the instruction, for example, the wristband and the ring in Table 1 may collect user pulse data from sensors of the devices and transmit the collected data to the first electronic device 101. When the AP 210 of the first electronic device 101 determines that a plurality of pieces of received data correspond to pieces of data received from the second electronic devices, which are most suitable for outputting a pulse, the AP 210 of the first electronic device 101 may calculate an average value of the plurality of pieces of data. The AP 210 of the first electronic device 101 may calculate an average value of a plurality of pieces of data and control the display unit to output the calculated average value for the user or perform an operation for displaying the data.

As shown in Table 1, the second electronic devices 104 may output different types of data. Each of the second electronic devices 104 may receive a signal of the first electronic device 101 and transmit data related to the signal to the first electronic device 101. At this time, the second electronic device 104 may transmit the data to the first electronic device on a predetermined cycle. The second electronic device 104 may transmit data to the first electronic device 101 on different cycles according to the data type. For example, pulse and heartbeat data types may be transmitted to the first electronic device 101 every second to monitor user health. The data type such as the number of operations may be transmitted to the first electronic device 101 every 30 minutes to monitor a quantity of exercise performed by the user. The data type such as a cholesterol level may be transmitted to the first electronic device 101 at each meal time. This is so the AP 210 of the first electronic device 101 can monitor which food is good for a following meal. Further, the data type such as body temperature may be transmitted to the first electronic device 101 every minute. This is so the AP 210 of the first electronic device 101 can monitor the user's health for the same reason as that of monitoring the user's pulse and heartbeat.

The various embodiments of the present disclosure for selecting the second electronic device 104 to I/O data can be applied to FIGS. 4 to 6 below.

FIG. 4 is a flowchart illustrating an operation of the first electronic device 101 according to various embodiments of the present disclosure.

Referring to FIG. 4, the AP 210 of the first electronic device 101 may determine the type of signal to be transmitted to the second electronic devices in operation 401. The electronic devices that can output the signal may vary depending on the signal type. After determining the signal type, the AP 210 of the first electronic device 101 may transmit the signal to the second electronic devices. In operation 403, the AP 210 of the first electronic device 101 may make a request for transmitting pieces of data related to the signal type to a plurality of second electronic devices. In operation 405, the AP 210 of the first electronic device 101 may receive the pieces of data related to the signal type from the second electronic devices.

Referring to FIG. 5, a plurality of second electronic devices may transmit/receive data, and determine to perform operations. In operations 501 to 502, a second electronic device A 104 a and a second electronic device B 104 b may transmit/receive at least one of a signal and data through BT communication. The second electronic device A 104 a may detect data to be output for a signal received from the first electronic device 101 in operation 503, although this is not illustrated in FIG. 5. In operation 503, the second electronic device A 104 a may transmit the detected data A to the second electronic device B 104 b which is different from the second electronic device A 104 a. The second electronic device B 104 b may receive the data A transmitted from the second electronic device A 104 a, and also may detect data B to be output for a signal received from the first electronic device 101 in operation 504, although this is not illustrated in FIG. 5. In operation 505, it may be determined whether data B has a higher priority than data A. The priority may be configured not to overlap a plurality of second electronic devices to output one output data. When a processor of the second electronic device B 104 b determines that data A has a higher priority than data B in operation 505, the second electronic device B 104 b may proceed to operation 506 and transmit a command performing an operation for data A. In operation 507, the second electronic device A 104 a may perform the operation for data A in response to the command received from the second electronic device B 104 b. When the second electronic device B 104 b determines that data A has a higher priority than data B in operation 505, the second electronic device B 104 b may proceed to operation 508 and perform an operation for data B. In operation 505, the process of determining the priority may include a simple comparison between data A and data B. Further, the process of determining the priority may include a process of comparing states of the second electronic device having transmitted data and selecting data transmitted by an optimal second electronic device.

Although FIG. 3 illustrates an operation performed by three electronic devices, a plurality of second electronic devices and the first electronic devices 101 may transmit/receive signals through BT communication. The second electronic device A 104 a may detect data A to be output for a signal, which is not illustrated in FIG. 6 but received from the first electronic device 101, that is, data A corresponding to a condition in operation 604. The second electronic device A 104 a may transmit data A to the first electronic device 101 by controlling the BT module 225. In operation 605, the first electronic device may receive data A from the second electronic device A 104 a. The second electronic device B 104 b may detect data B to be output for a signal, which is not illustrated in FIG. 6 but received from the first electronic device 101, that is, data B corresponding to a condition in operation 606. The second electronic device B 104 b may transmit data B to the first electronic device 101 by controlling the BT module 225. In operation 607, the AP 210 of the first electronic device 101 may receive data B from the second electronic device B 104 b. In operation 608, the AP 210 of the first electronic device 101 may determine priorities of data received from the second electronic device A 104 a and the second electronic device B 104 b. In operation 608, the process of determining the priority may include a simple comparison between data A and data B. Further, the process of determining the priority may include a process of comparing states of the second electronic device having transmitted data and selecting data transmitted by an optimal second electronic device.

When the AP 210 of the first electronic device determines that data A has a higher priority, the first electronic device 101 may transmit a signal performing an operation on a signal to the second electronic device A 104 a. In operation 609, the second electronic device A 104 a may perform the operation for data A. When the AP 210 of the first electronic device 101 determines that data A has a higher priority, the first electronic device 101 may transmit a signal performing an operation on a signal to the second electronic device B 104 b in operation 608.

Table 2 above may list sequences to select the second electronic devices based on each I/O function. Table 3 shows weighted values defined with Table 2. The weighted values in Table 3 may be changed by the user. The AP 210 of the first electronic device 101 may store the above tables in the cloud. The cloud may refer to an external service, not internal storage space, and the electronic device connected to a server may download or upload various types of information. The AP 210 of the first electronic device 101 may transmit a signal by controlling the BT module 225 to output data to the second electronic device 104 which is automatically determined according to Table 3 based on I/O functions.

The first electronic device 101 and a plurality of second electronic devices 104 may be connected through BT communication. The AP 210 of the first electronic device 101 may identify Tables 2 and 3 through the cloud. An operation for determining the second electronic device 104 may be performed by the cloud or the AP 210 of the first electronic device 101. Based on the weighted values of Table 3, a predetermined value is assigned to each state. Values from 1 to 5 may be assigned according to the selection sequences of Table 2. As a battery state grows closer to full charge, a high value is assigned. A high value may be assigned as 2, a medium value may be assigned as 24, and a low value may be assigned as 6. As the processor load becomes larger, a ‘high’ value is assigned. A high value may be assigned as 0.27, a medium value may be assigned as 0.5, and a low value may be assigned as 0.25. As a user preference grows, 1 is assigned. Values from 1 to 3 may be assigned. As the influence of the context becomes stronger, a high value is assigned. A high value may be assigned as 3, a medium value may be assigned as 2, and a low value may be assigned as 1. The assigned values may be changed by the user.

For example, the AP 210 of the first electronic device 101 may select the second electronic device 104 to output a time function. The second electronic device 104 may be determined according to the weighted value of Table 3. According to Table 2, the second electronic device 104 to be selected first to output time is a smart watch. Further, when a battery state of a smart watch is medium, a load degree of a processor is medium, user preference is low, and context is low, the following equation may be determined: (0.3×1)+(0.4×24)+(0.2×0.5)+(0.05×3)+(0.05×1)=3.48  Equation 1

Under the same conditions for outputting a time function, an equation to select a ring may be expressed below: (0.3×3)+(0.4×24)+(0.2×0.5)+(0.05×3)+(0.05×1)=4.08  Equation 2

When the first electronic device 101 or a cloud determines the second electronic device 104 by using a weighted value, the second electronic device 104 having a small calculated value is selected.
